try hda-jack-sense-test to fond out whether there is no Jack detection
for the line out jack
it is strange that you have two non detectable output pin complexes
internal speaker and line out
especially line in Jack support Jack detection but line out Jack did not
usually speaker is automuted when you plugged headphone or line out
post the output of pactl list
you have to ask the author of the patch why the line out Jack get the
pcm playback volume control instead of front playback volume since there
are headphone playback volume and speaker playback volume
